The coin is around 4 inches in diameter and 2-4 millimeters in width. Its fine for my collection but way bigger and flatter than expected. The details on the back are also less raised than the front.
Compared to other Alcove Vault deck boxes, this one is less sturdy than the other models. The box's flaps are foldable, making it hard to get to my decks sometimes. And because the token compartment is also flexible, my tokens often get trapped in that space, becoming convex and damaging my cards. Because of the latter, I can't recommend this highly, I'm sorry.
